求助 zabbix 监控hadoop 无法获取数据

i1zhuxian

参考这个网页的内容，hadoop的监控

有一部“zabbix_trap的数据类型，现在我们即将采用的是传统的在被监控端创建UserParameter的方式，所以一个很重要的地方需要做修改”
这个是指要修改为 zabbix agent吗？




然后下载脚本，修改……
最后还是没有获得数据，zabbix_get也不行，报key错误
[iyunv@htm1 ~]# zabbix_get -s hadoop1 -k min_free_storage_pct_node_name
ZBX_NOTSUPPORTED: Unsupported item key.

在zabbix-agent.log也发现来了大量的这个讯息……

……
这个要怎么修改呢 还是哪里出问题了？
